Trying to capture bad emails from Event ID 7004 (Exchange 2003)

Hey everyone,

We are now starting to send invoices to our customers from a database of emails we collected from them. I am seeing a TON of 7004's in the event log, and I want to make a list of all the emails that are bad (By finding 7004's with "no such user" etc).

Can this be done in powershell, or some sort of 3rd party Exchange app?

Don't know any way other than to manually remove each one from the Source Database. It doesn't have to be done all at once,...but as you get more done the list of 7004's will get smaller,...so the longer you work at it the smaller the job becomes

Note: Exchange is designed to be a Corporate Messaging System,....Exchange is not a mass-mailing system, and its design makes it a very bad for doing mass mailings. For example it is a heavy load to create a separate copy of the message for each recipient,...on the other hand if you try to dodge that by adding multiple users to the TO or CC or BCC Fields some receiving mail system will reject the message as SPAM (many limit it to 20 receipients).

The proper system for mass mailing is a List Server (of which,... Exchange is not one). A List Server is unique type of mail server specifically designed to handle mass mailing and many have an automated way to deal with "bad recipients" that automatically drop the recipient after a certain number of failures. Many ISPs have these and can offer them as a service.
